Marks of a True Conversion
Matthew 18:3 — “Verily, I say unto you, except ye be converted, and become as little children,
ye shall not enter into the kingdom of heaven.”

I suppose I may take it for granted, that all of you, among whom I am now about to preach the kingdom of God, are fully convinced, that it is appointed for all men once to die, and that ye all really believe that after death comes the judgment, and that the consequences of that judgment will be, that ye must be doomed to dwell in the blackness of darkness, or ascend to dwell with the blessed God, for ever and ever.

I may take it for granted also, that whatever your practice in common life may be, there is not one, though ever so profligate and abandoned, but hopes to go to that place, which the scriptures call Heaven, when he dies. And, I think, if I know any thing of mine own heart,
my heart’s desire, as well as my prayer to God, for you all, is, that I may see you sitting down in the kingdom of our heavenly Father. But then, though we all hope to go to heaven when we die, yet, if we may judge by people’s lives, and our Lord says, “that by their fruits we may know them,” I am afraid it will be found, that thousands, and ten thousands, who hope to go to this blessed place after death, are not now in the way to it while they live.

Though we call ourselves Christians, and would consider it as an affront put upon us, for any one to doubt whether we were Christians or not; yet there are a great many, who bear the name of Christ, that yet do not so much as know what real Christianity is. Hence it is, that if you ask a great many, upon what their hopes of heaven are founded, they will tell you, that they belong to this, or that, or the other denomination, and part of Christians, into which Christendom is now unhappily divided.

If you ask others, upon what foundation they have built their hope of heaven, they will tell you, that they have been baptized, that their fathers and mothers, presented them to the Lord Jesus Christ in their infancy; and though, instead of fighting under Christ’s banner, they have been fighting against him, almost ever since they were baptized, yet because they have been admitted to church, and their names are in the register book of the parish, therefore they will make us believe, that their names are also written in the book of life. But a great many, who will not build their hopes of salvation upon such a sorry rotten foundation as this, yet if they are, what we generally call, negatively good people; if they live so as their neighbors cannot say that they do anybody harm, they do not doubt but they shall
be happy when they die; nay, I have found many such die, as the scripture speaks, “without any hands in their death.”

And if a person is what the world calls an honest moral man, if he does justly, and, what the world calls, love a little mercy, is not and then good-natured, reacheth out his hand to the poor, receives the sacrament once or twice a year, and is outwardly sober and honest; the world looks upon such an one as a Christian indeed, and doubtless we are to judge charitably of every such person. There are many likewise, who go on in a round of duties, a model of performances, that think they shall go to heaven; but if you examine them, though they have a Christ in their heads, they have no Christ in their hearts.

The Lord Jesus Christ knew this full well; he knew how desperately wicked and deceitful men’s hearts were; he knew very well how many would go to hell even by the very gates of heaven, how many would climb up even to the door, and go so near as to knock at it, and yet after all be dismissed with a “verily I know you not.” The Lord, therefore, plainly tells us, what great change must be wrought in us, and what must be done for us, before we can have any well-grounded hopes of entering into the kingdom of heaven. Hence, he tells Nicodemus, “that unless a man be  born again, and from above, and unless a man be born of water and of the Spirit, he cannot enter into the kingdom of God.” And of all the solemn declarations of our Lord, I mean with respect to this, perhaps the words of the text are one of the most solemn, “except, (says Christ) ye be converted, and become as little children, ye shall not enter into the kingdom of heaven.”

The words, if you look back to the context, are plainly directed to the disciples; for we are told, “that at the same time came the disciples unto Jesus.” And I think it is plain from many parts of Scripture, that these disciples, to whom our Lord addressed himself at this time, were in some degree converted before. If we take the words strictly, they are applicable only to those, that have already gotten some, though but weak, faith in Christ. Our Lord means, that though they had already tasted the grace of God, yet there was so much of the old man, so much indwelling sin, and corruption, yet remaining in their hearts, that unless they were more converted than they were, unless a greater change past upon their souls, and sanctification was still carried on, they could give but very little evidence of their belonging to his kingdom, which was not to be set up in outward grandeur, as they supposed, but was to be a spiritual kingdom, begun here, but completed in the kingdom of God hereafter. But though the words had a peculiar reference to our Lord’s disciples; yet as our Lord makes such a declaration as this in other places of Scripture, especially in the discourse to Nicodemus, I believe the words may be justly applied to saints and sinners; and as I suppose there are two sorts of people here, some who know Christ, and some of you that do not know him, some that are converted, and some that are strangers to conversion, I shall endeavor so to speak, that if God shall be pleased to assist me, and to give you an hearing ear and an obedient heart, both saints and sinners may have their portion.
